Critically ill and hypotensive patients and those that meet systemic inflammatory response/
sepsis criteria should have an
ABG and lactate and cortisol levels measured.

An enzyme-linked immunoassay (ELISA) can detect ricin in human urine and serum at concentrations of 100 pg/mL or greater. Testing for ricin can be done by polymerase chain reaction (PCR) at a regional public health center laboratory by collecting 25 mL of urine.

Additional analytic methods may be available for ricin detection through the US Army Medical Research Institute for Infectious Diseases and the Centers for Disease Control and Prevention (CDC).

Imaging Studies

Imaging studies are not necessary because the beans generally are not detectable by plain radiography.

Procedures

Whole bowel irrigation (WBI) has been suggested as a possible treatment to ensure rapid and complete decontamination of the GI tract; however, the potential benefit (if any) remains unproven.

Consult with a medical toxicologist at the nearest regional poison control center before undertaking WBI.

WBI is accomplished by a continuous instillation of a polyethylene glycol electrolyte lavage solution through the gastrointestinal tract until the effluent from the rectum is clear.
